MODEL VERSION SYMBOL CHANNEL SPACING KEY PAD IC-F3061T U.S.A [USA-01] 15.0 kHz/30.0 kHz 10-key IC-F3061S 4-key IC-F3062T EURO [EUR-01] 12.5 kHz/25.0 kHz 10-key IC-F3062S 4-key IC-F3063T GENERAL [GEN-01] 12.5 kHz/20.0 kHz /25.0 kHz 10-key IC-F3063S 4-key To upgrade quality, all electrical or mechanical parts and internal circuits are subject to change without notice or obligation._ DANGER NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than 7.2 V. Such a connection could cause a fire or electric hazard. DO NOT expose the transceiver to rain, snow or any liquids. DO NOT reverse the polarities of the power supply when connecting the transceiver. DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector. This could damage the transceiver's front end. ORDERING PARTS Be sure to include the following four points when ordering replacement parts: 1. 10-digit Icom parts number 2. Component name and informations 3. Equipment model name and unit name 4.
